1 INFRARED HEATERS INFRARED HEATING Modern production processes need intelligent heat. And infrared thermal technology is efficient and precise. Today nearly every product that is manufactured comes into contact with infrared radiation during its manufacture. This trend is growing. Consequently, it is even more important that the correct heater is selected for every application. Infrared heaters cover the total spectrum of technologically-available wavelengths; we can help you find the optimal light source to suit your specific process application. Perfectly matched infrared lamps allow heating processes to be carried out at great efficiency with the right amount of energy. Reliable and reproducible manufacturing processes save money.

11 Infrared Heating Technology Technology that harnesses the power of infrared radiation can provide a powerful and efficient process heat source. Infrared heaters with IR technology are well-suited to a wide variety of applications and designed to transmit large amounts of energy quickly and with high efficiency. The particular wavelength of the infrared radiation has a critical effect on the effectiveness of the heating process. Infrared heaters, which are optimally matched to the materials to be heated, can provide energy savings of up to 50% over other technologies. Infrared heaters and infrared heating technology offer significant advantages: heat exactly where it is needed, with the optimum wavelength for the product and in line with the process. Dydac offers a complete range of heaters. We offer and design radiant heating products and equipment for industrial processes using proven infra red technology. This site offers information on our company and our complete product line including radiant heaters and heating equipment for process applications. We offer a full spectrum of high and low intensity heat for industrial processes As energy costs keep rising, you may consider efficiency measures to save energy and curb energy costs. Process heating accounts for a high percentage of energy use for most industries. Infrared heating technology, a clean and efficient heat transfer measure, is a great solution for your business.

12 Radiation Quartz Infrared Lamps Quartz infrared lamp is a high efficiency heating radiator that can heat up to 900 XC and cool down in seconds. It is made of high purity of quartz tube and Tungsten wire, filling with halogen gases inside the tube to protect tungsten wire and avoid filament oxidation when working. The emitted radiation of the lamps is much more effective than other heat transmission methods such as convection or conduction heating. Objects or their surfaces can be heated up from rather distant light source even through a glass window. Instant radiation from the lamp allows fast and flexible thermal processes The color temperature of quartz infrared lamps is around 2400 to 2500 XK. Quartz infrared lamp is a short wave IR emitter. The IR wavelength of the radiation emission is between 1 to 2 g. The lamp can equip with all kinds of ceramic caps. The length and material of the sleeves can be custom by customer's request The quartz tube can be coated with a layer of gold or ceramic as a reflector. The use of reflectors enables accurate aiming of the radiation and raising the infrared output. The average working life of the lamp lasts 5000 hours In addition to the standard straight tube, we also developed the quartz infrared lamps in various different shapes and sizes. Our products are available in different forms matched to different requirements. The lamps could be designed and manufactured according to the customer's request or drawing Infrared Emitters with Reflectors Features: All of our emitters can be coated with a layer of gold or ceramic as reflectors. The gold/ ceramic coating can concentrate the heat, increasing the effectiveness of the heat output. The emitters with coating are highly economical, converting practically all the consumed electrical power into heat For the emitters with high watt density or the surface temperature of the tube above 800 XC, we suggest to use ceramic coating as reflector because the temperature resistance is up to 1000 XC In addition to 180 X (half-tube) coating, we also manufacture 270 X coating or other customer specified degrees As energy costs keep rising, you may consider efficiency measures to save energy and curb energy costs. Process heating accounts for a high percentage of energy use for most industries. Infrared heating technology, a clean and efficient heat transfer measure, is a great solution for your business. In general, conduction and convection require heat-transmitting media such as solid, liquid, or gas. However, in the process of heat transmission by conduction and convection, most of heat is wasted. Radiation has higher

13 thermal efficiency by directly transmitting the heat to the object without requiring any media. Infrared radiation, one of the electromagnetic radiations, travels in a straight line at the speed of light from the heat source. In the process of travel, the energy of infrared radiation is not absorbed by air and directly transmits the heat to heated substance from the heat source; therefore infrared radiation is a very efficient source of radiant energy. Infrared radiation can save the process time and reduce the energy costs when applied in the industrial use. Comparison of Different Heating Source Hot Air Tubular Metal Heater Medium wave I.R.
